ANTl-RATTLER FOR THlLL-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 425,867, dated April15, 1890. Application filed August 28, I889. Serial No, 322,219- (Nomodel.)

To all whom it may concern:

Be it known that I, JOSEPH DOTY, a citizen of the United States, and aresident of Wells- Ville, in the county of Allegany and State of NewYork, have invented certain new and useful Improvements in Anti-Battlersfor Thill- Couplings; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in anti-rattlers forthill-couplings.

Heretofore it has been proposed to make the anti-rattler of rubber or toemploy a coiled spring, and it has been found by experience that therubber soon becomes, by reason of its exposure to the weather, hardenedand nonelastic, and consequently useless, as also the spring for thesame reason.

The leading object of my invention is the production of an anti-rattler,which will form a perfect cushion for the draw-iron, and will receiveand withstand the pressure brought to bear upon the anti-rattler, andalso withstand the damaging infiuence of the weather.

A further object of the invention is the production of a device whichcan be applied to any thill-coupling quickly and with ease, and whichmay be produced at a very low cost.

To attain the desired object the invention consists of an elastic blockor cushion adapted .to be inserted between the shackle and drawiron, andcontaining'and holding in place a coiled-Wire spring, which bearsnormally upon the said shackle and draw-iron.

In the accompanying drawings, forming part of this specification, and inwhich like letters of reference indicate corresponding parts, Figure 1represents a perspective-view of a thill-coupling with my anti-rattlerapplied. Fig. 2 represents a perspective view of the anti-rattlerdetached, and Fig. 3 represents a longitudinal sectional View thereof.

The anti-rattler consists of a rubber or elastic block or cushion A,having a coiled-wire spring B, placed therein in such a manner that theends bear against the thill and drawiron. In this instance the cushionis formed with a bore or passage 0 to receive the spring.

The device is placed in position, as shown in the drawings, and thedraw-iron exerting pressure against the spring compresses the same, andthe compressing of the spring causes it to form a firm cushion for thedrawiron, thereby effectually preventing all rattling and resisting theforce or strain brought to bear thereon.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An anti-rattler consisting of a rubber or other elastic blockprovided with a longitudinal bore, in combination with a coiled springpassing entirely through said bore, substantially as set forth.

2. An anti-rattler consisting of an elastic cushion having a boretherein, and a compound spring arranged in said bore, substantially asand for the purpose described.

3. In an anti-rattler for thill-couplings, the combination, with ashackle provided with the usual forwardly-extending ears, a drawironpivoted between said ears, of an elastic cushion disposed between theears of the shackle, said cushion provided with a longitudinal borehaving its front face concave to fit against the periphery of thedraw-iron eye, in combination with a coiled spring passing through saidbore, one end thereof pressing against the rear of the shackle and theopposite end against the periphery of the drauiron, substantially as setforth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

JOSEPH DOTY.
